lic it. known that l, TWILLIAM S. Possa', a citizen" of the United States. residing at Frettim, in the county of Kidder and State otl North Dakota, have invented certain new and useful Improvements in Rotary Plows: and I do hereby declare the following to be a full` clear, and exact description of thel invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention -has for its object to provide a simple, convenient and highly efficient r0- tary plow, and to' this end, the invention consists of the novel devices and combination 'of devices, hereinafter described and delined in the claims.

In the accompanying; drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation showing the improved rotary plow; Fig. 2 is a plan view of the same with some parts sectioned; Fig. 3 is a vertical section taken on the line ma :v3 of Fig. 2; Fig. 1 is a detail section on the line af* :v4 of Fig'. 2; Fig. 5 is a detail in section on the line fr rs-ofFg. 2; Fig. 6 is a detail in rear elevation showing the rear wheels and rear axle; Fig'. 7 is a detail in rear elevation showing the rear transverse bar of the machine frame, and Fig. 8 is a detail in section taken approximately on the line m8 w3 of Fig. 3, some parts shown in full vand some parts being broken away. For an important. purpose which Will hereinafter appear, the frame of the machine .is made transversely adjust-able, the rotary blade equipped plow drum is made extensible or longitudinally adjustable in a direction transverse of the machine., and preferably also, thc axles ofthe truck are made longitudinally adjustable.

The machine frame, as shown, is a rectangular structure made up of side bars 1 and adjustable front and rear end bars 2, as best shown in Figs. 2 and 7. These front and' similar driving sprocket 8.

J ournaled in suitable bearings on the 'side bars 1 f the machine frame, located between the front and rear axles and extended parallel thereto, is a drum driving shaft 9 providedl at its ends with sprockets 10 and 11. A. sprockety chain 12 runs over the sprockets 7 and 10, and a similar sprocket chain 13 runs over the sprockets 8 and 11, so that both the front and rear traction wheels 6 are rendered effective to driveI the said drum shaft 9. This drum shaft 9 is preferably made rectangular in cross-sect-ion and it is made up of a multiplicity of longitudinally alined sections having` overlapped ends detachably, but rigidly connected by nut-ted bolts 14, as best shown in Fig. 8.- The said drum shaft 9 should be vertically adjustable, and hence, it is journaled to bearings 15 that are mounted for vertical movements between vertical guide brackets 16 that ar(` rigidly secured to and depending,r from the side bars 1 of the machine frame. These vertically adjustable bearings 15 are connected tothe lower ends of links 17, the upper ends of which are connected to the lower ends 4of latch` levers 18 which, in turn, are pivoted to latch segments 19, rigidly secured on the said side bars 1. The latch levers 18' are adapted to be locked in different positions to the lock segment 19 and they serve to support the drum 'shaft 9 in different vertical positions, or for a purpose which will more clearly hereinafter ap pear.

The drum shaft 9 is extended through and carries avdrum'orflarge sleeve made up of a multiplicity Of-sections 20. which, at their f'f? abutting ends. are preferably provided with interlocking halfclutches 20a. The outer I tions'tof, which there may be one or more) are of the'same length as the intermediate vsections of the drum shaft 9, and the axles 4 and the end bars 2 are made adjust-able in units corresponding to the length of said intermediate drum sections. Otherwise stated,

" the machine frame and driving mechanisms are adapted to be adjustedlto vary thewidth ofthe machine according-'tosthe'ndmber of l outer-rends with heads 23. For each-pair of drum sections applied tothe drum shaft.

Each drum section is provided with ra- .disilly projecting pairs of hubs 2l, in which, as shown, the inner ends of heavy radially` .extended arms or spokes 22 are rigidly secured. The spokes 22 are provided at their spokes .22 there is a plovvr blade 24 provided on the inner edges and attheir backs with heavy sleeves or hubs 25 that are mounted for radial sliding movements on the Asaid spokes. Heavy coiled,l springs 26 placed on` the spokes -22 and compressed between the hubs 21. and 25; yieldingly hold the plow lblades 24Cv outward to their extreme limits,

I blade equipped drumis arranged to be rotated by the `connect/ions described, are indicated by'arrows marked on Fig. l. It is important to note that the said drum is rotated in a' directiogin which it tends to force the machine forward in the direction of its travel and this, as is evident, very greatly reduces the power required rto throw the ma'- chine forward.' In fact, the plow `blades are given a peripheral travel which is several times greater than the peripheral travel of the traction Wheels so that the sod or earth uplifted by the blades will be thrown upwardA and rearward and thereby disintethe drum.

grated and thoroughly mixed and deposited 1n loose form at the rear of the machine. If any of the plow blades should be "thrown against a rock, rut or other `obstruction in the ground through which the blade cannot out, it may yield and move radially toward the 'axis of-tle drum,shaft and 'thus prevent breaking vof the blade. The depth. of out may be vared'byvertical adjustments of The'power used to impart traveling moveyment tothe machine and rotary movement to,l the xblade equipped drum may be a trac- -ably secured to said tion engine carried by thenmachine, or the machine shown may be hitched to the rear or pushed in front of a traction engine. It may even be drawn' forward by hoises sofar asfmy invention is concerned.

It is-of course, usually desirable to cut as Wide-a furrow as possible, and the width of the furrow that canbe cut with acgiven source ,of power will depend on the condition of '[the soil. wider furrow can be cut than in dry hard soil, and a wider Vfurrow can be cut in previously plowed ground than can be cut through sod. To adapt the machine for these conditions of soil, it is made adjustable, as already described. 1t is evident 'that by altering or moving the intermediate drum sections and correspondingly adjustving the other parts of the machine, the

width ofthe furrow which will be cut b v the machine muy be very greatly varied.

lVhat I claim is:` A l. In a machine of the kind described, the combination with a truck, of a rotary drum 'carried by the truck frame and provided with radially project-ing and transversely spaced pairs of spokes, cutting blades having bearing .hubs slidably mounted on said pairs of spokes, and `springs on the Said spokes yieldingly pressing the said blades radiallyoutward, substantially as described. 2. In a machine of the kind described, the

In testimony whereof I atiiX my signature in presence of two witnesses.
